Replacing Hard Disk Drives
There are two hard drive bays in the system (see (1) and (2) in Figure 15). Each hard drive bay
supports a tray-mounted Ultra-320 SCSI disk drive with single connector attach (SCA)
interconnect. The drive tray is installed into the front of the chassis in the hard drive bay, and then
secured in place using the horizontal handle on the drive tray. A small lever on the front of the
system is then rotated into the horizontal position to connect the SCA connector on the system flex
circuit SCSI cable to the SCA connector on the drive. Ultra-320 SCSI technology (SCA
interconnect) or slower hard disk drives can be installed in this hard drive tray. The hard drive bays
are designed to accept 15,000 RPM (and below) hard drives that consume up to 18 Watts of power.
